DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Referring to FIGS. 1, 2 and 3, the present invention of an improved structure of a tube rack with telescoping function mainly comprises of an outer sleeve (1) disposed with an inner link (2) thereon, the inner link (2) extends from the external edge of the outer sleeve (1), inserts into the internal space of the outer sleeve (1) and is secured and fixedly disposed by a threaded sleeve (3); wherein, the outer sleeve (1) is a hollow cylinder structure, one end plane of the outer sleeve (1) has the thread teeth (10) for threading the threaded sleeve (3); the main function of the outer sleeve (1) is to secure the inner link (2) therein, and through the function of a telescopic shaft link (20) with a fitting spring (2 1) and a retaining seat (22), to enable the inner link (2) to slide and telescope freely inside the outer sleeve (1) up to a certain fixed point on the outer sleeve (1) for securing.

[0015] The inner link (1) comprises of a telescopic shaft link (20) with a press-button (200) thereon, fitted with a spring (21) and a retaining seat (22), disposed through the internal space of the inner link sleeve (23); the spring (21) is disposed on the telescopic shaft link (20) and exposes between the end with the press-button (200) of the inner link sleeve (23) and the press-button (200) so as to strengthen the recoiling ability of the telescopic shaft link (20) after sliding inside the inner link sleeve (23); the other end of the telescopic shaft link (20), relative to the end with the press-button (200), is connected with a retaining seat (22); the retaining seat (22) is a hollow sleeve, the lateral edge plane of the retaining seat (22) has several holes fitted with equivalent numbers of rolling beads (220); the rolling beads (220) are disposed at the holes and capable of protruding outside or hiding on the lateral edge plane of the retaining seat (22) for securing; the diameter of the upper segment of the inner link sleeve (23) fits with that of the inner edge plane of the outer sleeve (1) to facilitate the protruding inner link (2) to telescope and slide freely and straightly at the relative position on the outer sleeve (1), while the external view of the lower segment of the inner link sleeve (23) is of a conoid (230).

[0016] The threaded sleeve (3) is a hollow and through cylindrical structure with threads (30) therein; the threads (30) of the threaded sleeve (3) fit with the thread teeth (10) of the outer sleeve (1) for threading to facilitate the final length fixing movement of the telescopic tube rack of the present invention thereby to increase the functional integrity of the present invention.

[0017] Referring to FIG. 4, the retaining seat (22) structure of the present invention is a hollow sleeve; the lateral edge plane of the retaining seat (22) has a plurality of holes fitted with equivalent numbers of rolling beads (220); the rolling beads (220) are disposed at the holes and capable of freely protruding outside or hiding on the lateral edge plane of the retaining seat (22); furthermore, the upper end of the retaining seat (22) links with a telescopic shaft link (20); when trying to make the inner link (2) of the present invention into a protruding state, it is only necessary to depress the press-button (200) downward; after being depressed downward, the press-button (200) links the telescopic shaft link (20) as well as the retaining seat (22) to slide downward; the retaining seat (22) separates downward from the conoid (230), the rolling beads (220) roll into the lateral edge plane of the retaining seat (22) to hide naturally due to the separation from the forcing of the conoid (230) edge plane.

[0018] Referring to FIGS. 5 and 6, when the user wants to adjust the length of the present invention of the tube rack with telescoping function, it is only necessary to depress the press-button (200) downward to force the rolling beads (220) to naturally roll into the lateral edge plane of the retaining seat (22) and hide in a protruding state, and to adjust the inner link (2) straightly and freely to the proper length and height, then to release the press-button (200); at this time, since the recoiling force of the spring (21) will lead the retaining seat (22) to insert into the conoid (230) for telescoping; the force of the conoid (230) plane naturally drives the rolling beads (220) to protrude outside the lateral edge plane of the retaining seat (22); the fixing will be done through the pressing, engagement and securing between the rolling beads (220) protruding outside the lateral edge plane of the retaining seat (22) and the outer sleeve (10) and through the threading fix by means of the threaded sleeve (3).

[0019] Referring to FIG. 7, the present invention of an improved structure of a tube rack with telescoping function can be adapted to any structure to be adjusted according to the desired length or height in use, such as the adjustable structure bodies of the garment rack, the computer desk, the umbrella, the cane, the telescopic link, the luggage, the mob, the lamp link, the chair, the storage rack, etc., for having the function of increasing the supporting force and being easy to be raised or lowered; hereby the inventor only uses the function of the adjusting structure of a garment rack as the notation for the exemplary embodiment of the present invention; furthermore, in making the embodiment of the present invention, the objects such as an outer case (4) and others for decorating can be added according to the need.

[0020] In summation of the foregoing sections, the patent application of the present invention not only possesses the innovative concept and structure, but also has not been previously disclosed for the said equivalents and is an improved invention of advancement, more especially, the embodiment of the structure is simple and easy, capable of achieving the predicted efficiency, sufficient for eliminating the shortcomings of the conventional structure and is bestowed with extensive and practical functionality; therefore, the present invention not only is equipped with innovative requirements, but also possesses the double values of advance and practicability and is hereby submitted to the patent bureau for review and the granting of the commensurate patent rights.
